vehicle, more particularly a motor tricycle.

In the majority of motor vehicles there is no difficulty in suitably driving a spring mounted driving wheel, thepower transmitting mechanism being arranged horizontally and at right angles to the direction of action of the driving wheel springs. The conditions are however far more difficult when the driving mechanism has to act almost vertically, as is usually the case in a motor tricycle, in which the motor is arranged over the driving front wheel.

Now according to this invention the power is transmitted from the motor to the driving wheel axle through chain gear the wheels or sprockets of which are arranged at a definite andunvary ing distance apart. The driving wheel and its hub are also rigidly connected to the axle of the wheel. The elasdouble object; in the first place it allows the play of the axle and driving wheel relatively to the chain wheel, and secondly the inter* position thereof enables the vehicle to be started in a manner entirely free from shock or jerk-and the inequalities in the drive of the motor to be compensated or neutralized. This is of very great importanceinasmuch as it obviates all jerking. of the chain resulting from the chain having to take up all the shocks and jerks caused through the uniform speed of the vehicle owing to the momentum of the moving parts on one hand and the non-uniform or uneven action of the motive power on the other. In this way the improved driving arrangement insures a smooth transniissionof ower without any jerking of the chain, com ined with a spring or elastic action of the front or driving whee-l. One construction of the improved driving arrangement is shown in the accompanying drawings.

Figure 1 is a side elevation, Fig. 2 a view partly in front elevation and partly in section through the driving mechanism. Figs.

5 and 4 show the power-transmitting device in its position of rest and in the position it assumes while driving.

The front or driving wheel a is fixed on the axle c by means of the huh I). The axle c is supported by two laminated springs 03 carried by a longitudinal extension e of the front wheel fork The transmission of power-from the motor 9 is effected through a chain wheel h on thefmotor shaft, a dri'vring chain c and a chain wheel is mounted to rotate on a ring Z fixed in the front fork f Within the ring Z the lower part of the wheel fork f is formed with a slot or hole in size corresponding to the amount of play required by the elastic movement of the laminated springs (Z. The wheel 73 is furnished with lateral projections m connected by springs n to pins or projections 0 on a disk p which is fixed in the driving wheel hub b. Any desired number of springs n can be employed, in Fig. 3, six are shown, in F 1g. 4 only four.

By means of the improved driving ar rangement the transmission of power can be effected through a chain drive the sprocket Wheels of which do not move relatively except in a rotary sense, the elastic action of the driving wheel taking place through a laminated spring and the power transmitted axle secured thereto, springs carriedby said axle and having bearings thereon, said frame and driven wheel suspended by said springs substantially concentrically about and at a distance from said axle, permitting free play thereof relative to said frame at all times and a plurality of driving wheel propelling springs radially disposed on and connecting said driven and driving wheels.

2. A, motor vehicle comprising in combination a driving wheel, a disk thereon secured thereto, an axle secured thereto, a

spring mounted on said axle, a vehicle frame provided with an axle receiving ring, said ring carried and positioned by said spring substantially centrally about and removed from said axle and permitting free play thereof within said ring in' any direction at will, a driven wheel rotatably mounted on said ring,a plurality of springs connected respectivel with said driven and driving wheels, an a motor on said frame connected with said driven wheel. v 8. A motor-vehicle comprising, in combination, a forked frame provided with a curved axle bearing receivin area, an axle,

a wheel fixed thereto, a cus ioned bearin for the axle carried by said frame in sai area permitting gyrator movement of the 20 wheel relative to the ve icle frame, and. a driven wheel mounted torotate about said. area, and resilient driving means between said driven wheel and axle.
